This dissertation consists of three studies exploring factors affecting whether, when and how students engage in sense making in science disciplines, and the epistemological components of instruction that impact their engagement. Each study is grounded in science education reform efforts, including the Next Generation Science Standards (NGSS),…

Since the 1980s, studies have increasingly shown that traditional teaching causes a deterioration in students' conceptions of physics and of learning physics. The present study examined the influence of an intervention on high school students' conceptions of physics and of learning physics. The intervention included two components: a unique design…

We present our outreach program, the "Thailand-UK Python+Astronomy Summer School" (ThaiPASS), a collaborative project comprising UK and Thai institutions and assess its impact and possible application to schools in the United Kingdom. Since its inception in 2018, the annual ThaiPASS has trained around 60 Thai high-school students in…

Background: Being able to think independently is a must for students to construct new knowledge in their minds. Self-explaining is a constructive learning strategy that encourages students to think for themselves and to make inferences that go beyond the given information. The Self-explain--Discuss--Re-explain (SDR) strategy adapted from…

In 2017 the University of Utah experienced a tragedy which catalyzed already active changes in the department. In the aftermath, admissions to the graduate program was paused while new policies were developed and implemented. This article outlines this change process through the perspectives and accounts of those involved. Through in-depth…

This research aims to analyse the process of grasping the Solar System by the students during their learning activities in which we used an animation film and other educational means (geographic globe, schematic drawings, 3D model, etc.), as well as the results obtained. In order to achieve this goal, we organized an action-research within…

[This paper is part of the Focused Collection on Astronomy Education Research.] In this paper we discuss the design and development of a learning progression (LP) to describe and interpret students' understanding about stellar structure and evolution (SSE). The LP is built upon three content dimensions: "hydrostatic equilibrium";…

Pre-service primary teachers mostly have negative attitudes towards science teaching and learning, and their science background is usually low. This usually results in them feeling unable or unconfident to teach science at school. A previous step to improve their willingness to teach science to children is that they feel they can learn in-depth…

To determine the extent of astronomy teaching in Quebec's schools, we conducted an online survey of 500 Québec's elementary (K-6) teachers between January and March 2015. With a 35-items questionnaire, we wanted to find out how these elementary teachers teach astronomy (or not) to their classrooms, what is their background in Science &…

This study focused on how culture of peace and care for the planet earth variables predicted public coeducational secondary school students understanding of chemistry concepts in Anambra State of Nigeria. Three research questions guided the study. It was a survey and correlational research designs that involved sample of 180 drawn from six schools…

The "Next Generation Science Standards" identifies argumentation as a central practice, and, subsequently, energizes teachers to develop students' capacity to write well-reasoned arguments and support their claims with relevant evidence. These skills now expected in the science classroom have long been central to instruction in…

This paper reports on the results from administering a modified version of the Introductory Astronomy Questionnaire (IAQ) to middle school students and preservice science teachers in Norway. Ranking tasks formed a key part of the instrument, and we detail a new method for analyzing ranking task data. One of our main findings was that even after…

Although physics education researchers often use workshops to promote instructional change in higher education, little research has been done to investigate workshop design. Initial evidence suggests that many workshop sessions focus primarily on raising faculty's awareness of research-based instructional strategies, a fairly straightforward goal…

In this work we study how different motivations of learners relate to their engagement in a massive open online course (MOOC). The research was conducted in a cohort-based astronomy MOOC "Astronomy: Exploring Time and Space" provided through the Coursera platform. In order to discern motivations of course participants, the Science…

The purpose of this study was to explore the effects of context-based learning approach (CBLA) on 5th grade students' misconceptions about 'the umbra, solar and lunar eclipses'. In this study, a quasi-experimental methodology pre-test and post-test design was utilized with control and experimental groups. The study was conducted with 48 5th grade…
